ROOF SEAMING TOOL Filed March 23 1958 Patented Jan. 10, 1939 PATENT OFFICE ROOF SEAMING TOOL George W. Wiese, Eau

Application March 23,

1 3 Claims.

The present invention relates to roof seaming tools of a type embodying a pair of pivoted jaw members adapted for engaging opposite sides of the upstanding roof seam to bend the same angularly into interlocking engagement.

The primary object of the present invention is to provide a roof seaming. tool embodying an extension on one of the jaw members adapted to extend downwardly along one side of the upstanding roofing seam for engaging thelatter to prevent slipping! of the tool from the seam during the bending operation.

A further object is to provide. a tool of this character of simple and practical construction, which is strong and durable, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation of the tool 20 is more fully hereinafter described and claimed,

reference being had to the accompanying drawing forming. part hereof, wherein like numerals refer to like parts throughout and in which- Figure 1 is a side elevational View of the tool with parts broken away and shown in section,

Figure 2 is an end elevational view.

Figure 3 is a similar View showing the initial roofing seam engaging operation of the tool.

Figure 4 is a similar view showing the completion of the initial bending action of the roofing seam. Figure 5 is a transverse sectional view through a roofing seam showing the same in completed form, and

Figure 6 is a side elevational view of a modified form of the tool embodying a detachable jaw extension.

Referring now to the drawing in detail, wherein for the purpose of illustration I have disclosed the preferred embodiment of the invention, the numerals 5 and 6 designate a pair of cooperating jaw members of elongated formation, the inner ends of each of which are provided with aligned eyes I through which a pivot pin or bolt 8 is inserted to provide for the pivotal action of the jaw.

From an intermediate section of each of the jaws, sockets 53 extend for receiving a manipulating handle W. The foregoing describes a conventional type of roof seaming tool, the present invention comprising an extension II for one of the jaws, said extension being of elongated form and secured along one of its longitudinal edges l2 to the outer surface of the jaw, the other edge of the extension ll projecting beyond the edge of the jaw in a manner as will be apparent from 1938, Serial No. 197,750

an inspection of the Figures 1 and 2 of the drawing.

The inner surface of the extension H is concaved transversely as shown at l3 with the free edge of the extension projecting. in a direction 5 toward the opposite jaw and substantially in alignment with the opening between said jaws, as clearly shown in Figure 2.

The. tool is designed for use in bending the upstanding seams of a sectional sheet metal roof 10 into interlocking engagement, the sheets being preformed and provided with upstanding seam joints along their longitudinal edges in the manner shown in Figures 3 and 4, one section of the roof being indicated at [4.

The section I4 is formed with an upstanding seam section l5, bent horizontally at I6 and downwardly at H to form a depending flange, the seam thus being of inverted channel form, as shown in Figure 3. The section I8 is also pro- 20 vided with an upstanding seam section !9, terminating in an upper horizontal section l9 fitted in the channel of the seam I5.

In order to lock the upstanding seam thus formed, the roof seaming tool is placed on the 26 upstanding scam in the position shown in Fig,- ure 3 of the drawing, with the extension ll contacting the vertical side of the seam l5 and the opposed jaw contacting the depending flange ll whereby it will be apparent that the closing ac- 30 tion of the handle will cause the flange I! to be bent upwardly and inwardly under the end IQ of the adjacent roofing section, the extension ll serving. to prevent slipping of the tool from the seam. Upon the completion of this initial bending action the seam will be closed in the manner as shown in Figure 4.

Following this initial bending action the tool is turned into a reverse position with the extension ll engaging the upper surface of the horizontal portion [6, as shown in Figure 4, whereby the latter is bent downwardly against the upstanding portion of the. seam into a position as shown in Figure 5 to thus form a double lock seam.

In the form of invention illustrated in Figure 6 of the drawing, in place of a permanently attached extension H affixed into one of the jaws, a plurality of attachments 20 are provided, said attachments being of substantially U-shaped form with the bight portion 2| secured in a longitudinal position against the outer surface of the jaws 6 by means of screws or the like 22 and the fingers 23 projecting outwardly beyond the longitudinal edge of the jaw and curved inwardly substantially in the form as shown in Figure 2.

It is believed the details of construction and manner of use of the tool will be readily understood from the foregoing, without further detailed explanation.

Having thus described the invention, what I claim is:

1. A roof seaming tool comprising a pair of elongated jaws pivotally connected to each other along one of their longitudinal edges, one of said jaws having an extension along its free edge with the free edge of the extension projecting beyond and terminating parallel to the free edge of the other of the jaws and curved transversely in a direction toward said other jaw for contacting the work at a point beyond the jaws and adapted to cooperate with the other of said jaws during initial closing movement, said jaws cooperating with each other independently of the extension during subsequent closing movement.

2. A roof seaming tool comprising a pair of elongated jaws pivotally connected to each other along one of their longitudinal edges and a plurality of fingers secured to the outer surface of one of the jaws and projecting beyond the free longitudinal edge of both jaws and curved in a direction toward the other of said jaws, for contacting the work at a point beyond the jaws and adapted to cooperate with the other of said jaws during initial closing movement, said jaws cooperating with each other independently of the extension during subsequent closing movement.

3. A roof seaming tool for channeled roofing seams in which one edge of the channel is free and depends downwardly, said tool comprising a pair of horizontally elongated pivotally attached jaws, one of said jaws embodying a main jaw structure and an extension, said extension projecting beyond the free edge of both jaws and curved in a direction toward the other jaw, and cooperating therewith to engage the vertical sides of the seam for bending the free edge of the seam inwardly during initial closing movement of the jaws and said main jaw structure engaging the top of the seam and cooperating with said second jaw to bend said free edge upwardly against the top of the seam during continued closing movement of said jaws.
